To increase the specific energy of commercial lithium-ion batteries, silicon is often blended into the graphite negative electrode. However, due to large volumetric expansion of silicon upon lithiation, these silicon–graphite (Si–Gr) composites are prone to faster rates of degradation than conventional graphite electrodes. Understanding the effect of this difference is key to …
A process known as "calendar aging" refers to battery degradation that happens regardless of use. It is largely due to growth in the protective layer around the anode (SEI). This protective layer is made up …

Like most of the effects involved in Lithium battery degradation, Lithium plating is not a thing that happens at a discrete, definable threshold. It has been observed at C-rates above 2.0 even at 50C (122F) (which is why Tesla preheats the battery to such high temps when navigating to a Supercharger). It has been observed at 25C (77F) at C ...

Winter range is roughly half of summer, maybe even more if you have an LFP pack and it''s extremely cold (below -30). At least, that''s been my experience. It''s a combination of wind drag, softer winter tires, bad roads, and frozen everything in the car, on top of the direct effect of a cold battery, which is increased impedence. Slower ion flow ...
LFP (Lithium Iron Phosphate) Batteries. Lithium Iron Phosphate (LFP) batteries are another type of lithium-ion battery, known for their long cycle life, safety, and good thermal stability. Like NMC batteries, ''LFP'' also describes …
As for the cathode, ageing effects at the graphite anode lead to a modification of the electrode properties with time and use. Ageing effects that may occur during storage (e.g., self-discharge, impedance rise) will affect the calendar life of the battery, whereas the cycle life is in addition influenced by ageing effects that may occur during use (e.g., mechanical …
